Read More2016-11-1 · 1. Introduction. Froth flotation is the selected method for the separation of quartz and feldspar. In the conventional process, feldspar is floated from quartz by using hydrofluoric acid (HF) as activator for the feldspar and a cationic collector (amine) at pH 2–3 (O’Meara, 1939).Sandvik (1979) reported that HF creates a large difference in the minerals’ zeta

Read More2018-11-1 · Intensified flotation of fine feldspar. Slimes in feldspar flotation (generally −38 μm size for feldspar mineral) have a negative effect on flotation by coating the feldspar surfaces owing to electrostatic interaction and decreased flotation recovery (Bandini et al., 2001, Karaguzel et al., 2006, Xu et al., 2003). Recovering feldspars from ...
